SRAM is excited to announce that, starting in January 2012, production of all X9 10-speed and 9-speed trigger shifters (front and rear shifters, all current colours and speeds—2x10, 3x10 and 3x9) will be upgraded, using the same pull lever ball bearing technology used in XX and X0 shifters. The ball bearing replaces a bushing, resulting in a more solid feel, more precise shifting, and overall higher performance.
